Nondisp pilon fx l tibia, 7thN

This code describes a pilon fracture of the left tibia that is not displaced, meaning the bone fragments are still in their normal anatomical alignment. It specifically indicates that this is a subsequent encounter for an open fracture of Gustilo-Anderson type IIIA, IIIB, or IIIC, and that the fracture has failed to heal properly (nonunion).

Use this code when documenting follow-up care for a patient with a previously diagnosed open pilon fracture of the left tibia (types IIIA, IIIB, or IIIC) where the fracture fragments are currently nondisplaced, but the bone has not united. This applies to situations where the patient is still receiving active treatment for the nonunion, such as further surgical intervention or prolonged immobilization.

• Always confirm the laterality (left tibia) and the displacement status (nondisplaced).
• Ensure the documentation clearly states "nonunion" and specifies the original open fracture type (IIIA, IIIB, or IIIC).
• This code is for subsequent encounters; an initial encounter for this specific condition would use a different code.
